" nndns'rAsLn ennoiewxnn HOLDER.

To all whom it may concern." a

Be it known that I, WILLIAM S. PE'rnnsnN, a citizen of the United States, res'iding at Fort Dodge,in the county of Viebster and State of Iowa, have invented certain new and useful Improvements in Adjl'lstable Cheekire Holdersyof which the tollowing is a specification. 1

This invention relates to aeheek-Wire holder and more particularly to anadjust able holder for a cheelewire for use in conneetion with a corn planter.

The primary object of the invention is to provide an adjustable eheelpwire holder having means for properly tensioning the cheek-wire as it is stretched across the corn iield, the adjustable tensioning means being designed to perniit thecheek-wire tohe equally tensioned as it is moved from one position to another for regulating and governing the rows of planted corn. 1

A further oh'ect of the invention resides in. the provision of a stake carrying a tube which incloses a spring for providing va rious tensionson the cheek-wire.

its a turther object of the invention the device is provided with looking dogs wl'iioh are adapted toregister with teeth disposed in position for permitting the tension of the wire to be regulated to any desired tension.

Fig. 4 is afragrnentary section on the line t- 'l of Fig.1.

The stake l is provided witha sharpened end 2 forpernutting the stake to be driven into the ground at the side of the'eorn field. For manually forcing the stake into the ground, a foot-plate 3 isprovided andex tends laterally from a collar a slidably mounted upon the rod 1 and secured thereto by a set serewo. The upper end of therod 1 is provided with a loop 6 by which the stake may he withdrawiti from the ground when desired.

A casing 7, of tubular forination is pro-' vided with openings 8 through whiehis ex tended the stake l and the casing is thereby permitted to slide upwardly or down wardly for adjusting the easing to the de sired height. The casing isprovlded OII IiS Specification of Iiettersfatent. Application filed may 18, 1916. Serial No. 109,934.

topwith a longitudinal slot 9 which eX- tends from the upper end of the casing for- \vardly toa point adjacent one of the openings 8. integrally formed with the casing 7 at each sideoi the slot 9, is a pluralityof notches 10,'the notches on one side ofthe slot .heing out at the reverse angle to the note'heson the opposite side thereoiii The torward end oi-the casing is closed-by an end wall 11 which provided With a pair of openings,- laterally spaced apart and through which are extended the rods12 which arealso laterally spaced apart and The forward disposed within the casing. ends of the rods 12 carry a plate 13 to which is secured the eheelewire holding hook 14. The bill of the hook is bifurcated to permit theinsertion of the cheek-wire and, when one of the knots in the check-Wire is dis POSGClWltlllll the hook and the cheek-Wire extended through the bifurcation, any acoldental displacement of the wire from the hook willbe preventedi Mounted within the casing, adjacent the rear end thereof, is a sliding bushing 15 to which secured theends of the rods 12;

Secured to the bushing 15 and extending upward-1y through the slot 9 in the casing, V

a locking arm 16 to the upper end 01? which is plvoted the locking dogs 17 and 18, 'Wlllfjll 18 adapted to reglster with the notches 10 on the casing.

-Arranged Within the easing,,and interposed between the stake 1 and the bushing 15 is a coiled expansion spring 17, the coils of which surround the rod 12. This spring permits the same; tension to be maintained at all times upon theeheclewire. a it In operating the device, in connection with the planting of a row of corn, the stake in the'eheek-wire caught into the hookil l.

"Theloeking' arin 16 will loe moved rearwe rdly to apredetermlned distance from the end of the easlng and the loelnng'dogspermitted to drop into engagement with the notches thereby holding the hook at a certain distance from the end of the casin The opposite ends of the cheek-Wire will he fixed in any suitable manner to the opposite This may be accomplished by drivinga stake intothe ground at the desired point and fixing the end of the "cheek-Wire to the stake.

r By referring to Fig. 1 of the drawing 1t will be first driven into the groundatthe edge of the eornfieldyand one 01' the knots Fig. 4 of the drawing. The coil expansion spring presses the pawl 17 into engagement with its notch, while a slight forward move.

ment of the rods 12 ispermitted, this move ment being limited by the distance theedge of the pawl 18 is disposed from its notch.

The locking dog l7. prevents the expansion' spring 17 from pulling the hook beyond the desired point while the planter is pro gressing from one knot to the next. The locking dog ,18, in registration with the notches on the opposite sideof the slot 9, prevents the check-Wire from becoming slackened when the planter strikes one of the knots in the check-wire. Each of the locking dogs are provided with a lifting wire 19 connected to a ring 20 through the medium of which the locking dogs may be drawn out of engagement with the teeth or notches when moving the locking arm from one point to another.

I claim: a V

1. A cl1eckwire holder including a stake, and tensioning means carried by and dis posed. at right angles to the stake and adapted to be secured .to a check-wire, in

cluding a pair of locking dogs for holding the check-wire at apredetermined tension.

2. A check-wire holder includinga stake, a casing disposed at right angles to the stake and provided with oppositelydisposed apertures through which the stake is extended, said casing being also provided with a plurality oflongitudinally arranged notches, tensioning means arranged within-the casingand adapted to be secured to a checkwire, said means including a locking element for holding the check-wire at a pre-deter mined tension provided by saidtensioning means.

3. A check-wire holder including a stake, a tubular casing carried by the stake and disposed at right angles thereto, said casing being provided with a longitudinal slot, a plurality of notches provided on the easing, said notches being arranged in a pair of longitudinal rows on opposite sides of said slot, and tensioning means arranged within thecasing and adapted to be connected to a check-wire for permitting a tension tobe maintained on the check-wirmand apair of locking dogs pivotally carried by the tensioning means and adapted to register with said notches.
